3. Write a balanced chemical equation for the reaction in step 1.
CH₂=CH₂(g) + H₂O(g) ⇌ CH₃CH₂OH(g)
4. Write a balanced chemical equation for the reaction in step 2.
3CH₃CH₂OH(l) + 2Cr₂O₇²⁻(aq) + 16H⁺(aq) → 3CH₃COOH(l) + 4Cr³⁺(aq) + 11H₂O(l)
(Using acidified potassium dichromate(VI) as the oxidizing agent)
5. Write a balanced chemical equation for the reaction in step 3.
CH₃COOH(l) + CH₃CH₂OH(l) ⇌ CH₃COOCH₂CH₃(l) + H₂O(l)
6. Write a balanced chemical equation for the reaction in step 4.
CH₃CH₂OH(l) → CH₂=CH₂(g) + H₂O(l)
7. Write a balanced chemical equation for the reaction in step 5.
CH₂=CH₂(g) + HBr(g) → CH₃CH₂Br(l)
8. Write a balanced chemical equation for the reaction in step 6.
CH₃CH₂Br(l) + KCN(alc) → CH₃CH₂CN(l) + KBr(aq)
9. Write a balanced chemical equation for the reaction in step 7.
CH₃CH₂CN(l) + 2H₂O(l) + H⁺(aq) → CH₃CH₂COOH(l) + NH₄⁺(aq)
(This is for acidic hydrolysis)
